Not suprising to be honest. In middleschool and highschool I would stay up even later. Wake up for school at 7, get there by 8, class till 3, after school activity till 5 or 6, done with dinner by 7, two hours or so of half assed work (takes longer the more half assed), then 9 o clock would signal that the rest of the day belonged solely to me and my interests, and I would be on the laptop or play video games untill whenever I got tired. Usually I'd clock around 5-6 hours a night of sleep during the week, and make it up by sleeping close to 10 on the weekends.

College set me straight with sleeping, though. I was able to schedule classes no earlier than 10:30, and if I went out late into the night and got hammered I could sleep in on a whim without consequence. I was also able to have nap time again. Definitely struggled getting sleep with a full time job now, but its been getting better. Everyone where I work has their own schedules. Couple of us are here at 7, me and others don't get in till 10-10:30. Sometimes I work till 7, most of the time I leave by 5, and sometimes I leave at 3. Rigidity kills the soul.

I pulled all-nighters in grade school to maximize my media intake (in this case browsing message boards) while still getting homework done.

Guessing kids these days do the same to stay on top of snap, insta, tiktok, reddit, etc.
